Depth Filters

  • Premium Cotton Media — Cotton's fine fiber diameter anoliophyllic properties make it an ideal medium for hydrocarbon filtration. We use only natural cotton fibers (not textile waste) in our products
  • Local Wood Fiber — Wood absorbs water and acids (extending lube oil drain intervals) and improves the filter's flow characteristics. Our wood is grown and processed here in Wisconsin, for excellent cost control.
  • Socks & Center Tubes — Our socks and tubes are made in-house which provides cost control, quality, and availability.
  • String Spacing — Filtration Systems has string spacing every ¼-inch which is 4-times higher than industry norms. This result in a more stabilized media and higher filtration efficiency.
  • Swirl Flow Design — Filtration Systems' patented Swirl Flow™ depth elements are a dramatic break-through in filter technology. By alternating layers of low and high density media, and balancing the ratio of circumferential to radial flow, the media layers progressively load with dirt, like peeling an onion. The result is an incredibly long-life filter, designed for reliable performance at low cost. Our depth filter elements last longer and perform better than pleated paper elements
